Help with alternator bracket

[ctbZ]

Which is the correct alternator bracket for a '70 lt1 camaro (assembly-flint, Mich. Feb 14). I've seen three different types: one with one hole, one with two holes, and the other with three.

Thank you for your help.

69's had the one hole bracket, and all the '70 Z28's I've seen had the two hole version.
